- A conventional washing machine typically includes a cabinet, a top cover coupled to a top of the cabinet and a lid hingedly secured to the top cover to open and close an opening formed at the top cover.
-
FIG. 1 is an exploded perspective view illustrating atop cover 1, alid 10 and ahinge member 20 coupling thetop cover 1 with thelid 10.FIG. 2 is an enlarged view illustrating thehinge member 20. - In reference to
FIGS. 1 and 2 , thelid 10 of the conventional washing machine includes aninsertion hole 11 and acoupling hole 12. Theinsertion hole 11 is formed at a side portion of thelid 10 and thehinge member 20 is inserted in theinsertion hole 11. Acoupling member 15 passes through thecoupling hole 12 for thehinge member 20 to be coupled to thelid 10 securely in a state of being inserted in theinsertion hole 11. - The
hinge member 20 includes acoupling part 21 and ahinge part 25. Thecoupling part 21 is inserted in theinsertion hole 11 to be coupled thereto. Thehinge part 25 is provided at a predetermined portion of thecoupling part 21 and it rotates about thetop cover 1. - The
coupling part 21 is rectangular-plate-shaped and it is formed at a position, corresponding to thecoupling hole 12 formed at thelid 10 when inserted in theinsertion hole 11 of thelid 10. Here, thecoupling part 21 includes a throughhole 22 through which thecoupling member 15 passes. - The
hinge part 25 is cylinder-shaped for thelid 10 coupled thereto by thecoupling member 20 to rotate relatively with respect to thetop cover 1. - The
lid 10 is seated on thetop cover 1 and alid seating surface 2 is recessed at thetop cover 1 to a predetermined depth to seat thelid 10 thereon. Here, the recessed depth of thelid seating surface 2 is identical to the thickness of thelid 10 such that an upper surface of thetop cover 1 may be formed smooth when thelid 10 is closed. - A user should lift the
lid 10 to open thelid 10 and thelid 10 rotates about thehinge member 20. - However, if the user takes off his/her hands from the
lid 10, thelid 10 will fall a predetermined height. If thelid 10 falls only to be bumped into thetop cover 1, the force corresponding to the weight of thelid 10 is applied to thehinge member 20 and the force applied to thehinge member 20 is transmitted to thetop cover 1. - When the user drops the
lid 10 free to close, crack might be generated at the lid or thetop cover 1. - The reason why the crack is generated at the lid or
top cover 1 is that the shock applied to thehinge member 20 is transmitted directly to thelid 10 ortop cover 1 because thehinge member 20 is designed to improve only strength. - Accordingly, the present invention is directed to a washing machine.
- An object of the present invention is to provide a washing machine capable of improving a structure of a hinge member and to prevent damage of a top cover or lid which might be generated during the opening/closing of the top.

washing machine 100 and lifts thelid 200 upward to open theopening 121. Then, the user loads the laundry into thetub 130 through theopening 121 and puts thelid 200 downward to close theopening 121. Hence, if the user inputs a corresponding washing condition at thecontrol panel 122 and pushes a start button, thewashing machine 100 is put into operation according to the input condition. - After washing and dry-spinning cycles, the user lifts the
lid 200 again to open theopening 121 and unloads the washed laundry. Then, the user puts thelid 200 down again and closes theopening 121. - Next, in reference to
FIG. 4 will be described ahinge member 300 coupling thelid 200 to thetop cover 120 for thelid 200 to open and close thetop cover 120 and the coupling structure between thelid 200 and thehinge member 300. - The
lid 200 includes aninsertion hole 230 and acoupling hole 240 and both are provided at a side portion of thelid 200. Thehinge member 300 is inserted in theinsertion hole 230 and acoupling member 250 passes through thecoupling hole 240 for thehinge member 300 being inserted in theinsertion hole 230 to be securely coupled with thelid 200. - The
hinge member 300 includes acoupling part 310 and ahinge part 320. Thecoupling part 310 is inserted in theinsertion hole 210 of thelid 200 and thehinge part 320 rotates with respect to thetop cover 120. - The
coupling part 310 of thehinge member 100 is rectangular plate shaped. Because of that, if thelid 200 is rotated after thecoupling part 310 is inserted in theinsertion hole 230, the hinge member 30 is rotated together with thelid 200. - A through
hole 311 is provided at a portion of thecoupling part 310 which is corresponding to thecoupling hole 240 formed at thelid 200 and thecoupling member 250 passes through the throughhole 311. - The
hinge part 320 ishinge securing part 127 formed at thetop cover 120 such that thelid 200 coupled to thehinge member 300 may be rotated relatively with respect to thetop cover 120. - The user typically lets the hands holding the
lid 200 off from thelid 200. If then, thelid 200 is dropped a predetermined height and a shock corresponding to the weight of thelid 200 is transmitted to thehinge member 300 and the shock transmitted to thehinge member 300 is transmitted to thelid 200 and thetop cover 120. - The inventor has studied the
hinge member 300 having a structure capable of minimizing damage of thelid 200 or thetop cover 120 because of the shock generated when the user closes thelid 200. the inventor found out that the conventional hinge member is fabricated only to improve the strength and that thelid 200 ortop cover 120 could damage because of the shock transmitted to the lid or thetop cover 120 again after having been transmitted to thehinge member 200, which is generated when thelid 200 collides against thetop cover 120, accordingly. - The inventor has been studied the structure of the
hinge member 300 capable of minimizing the damage of thelid 200 ortop cover 120, especially, has experimented various types of thehinge part 320 to increase the elasticity of thehinge part 320. - In the experiment performed by the inventor, the
conventional hinge member 20 shown inFIG. 2 will be categorized as a control group and sevendifferent hinge members 300 having different shapes ofhinge parts 320 shown inFIGS. 5 a to 5 g will be categorized as experimental group. - When the
hinge member 300 of each experimental group is used in thewashing machine 100, the shock applied to thelid 200, thetop cover 120 and thehinge member 300 is measured. - A specific method of the experiment will be explained.
- The experimenter opens and closes the lid repeatedly to suppose that the user opens and closes the
lid 200. Here, thelid 200 in a state of being open is rotated and bumped against thetop cover 120, which almost identical to the case in that the user lets his/her hands off from thelid 200. To make experimental conditions identical, the experimenter is changed every 100 times. After repeating the 100 times of opening/closing thelid 200, average values of the shock applied to thelid 200, thetop cover 120 and thehinge member 300 are calculated. - The inventor of the present invention performed the experiments, changing three elements to increase the elasticity of the
hinge part 320. - First, a
slot 321 is provided at thehinge part 320 to increase the elasticity of thehinge part 320. Theslot 321 is formed through thehinge part 320, substantially perpendicular to a plane formed by thecoupling part 310, and it is formed horizontally in a longitudinal direction of thehinge part 320. - Second, a
cut part 322 is provided at thehinge part 320 and a predetermined portion of thehinge part 320 is cut to increase the elasticity of thehinge part 320. Thecut part 322 is substantially perpendicular to the plane formed by thecoupling part 310. In addition, thecut part 322 is formed by cutting some portion from a border between thecoupling part 310 and thehinge part 320 to a predetermined length. - Third, the length of the
hinge part 320 is increased to increase the elasticity of thehinge part 320. The length of thehinge part 25 included in the control group is 11.5 mm and the length of thehinge part 320 included in the experimental group is 14.5 mm, which is increased as much as 3 mm. - The seven experimental groups are fabricated, changing at least one of the three elements.
- The
experimental group 1 shown inFIG. 5 a includes theslot 321, not changing the other elements. - The
experimental group 2 shown inFIG. 5 b includes thecut part 322, not changing the other elements. - The
experiments group 3 shown inFIG. 5 c includes both of theslot 321 and thecut part 322 formed simultaneously, not changing the length of the control group. - The
experiment group 4 shown inFIG. 5 d has the increased length. - The
experiment group 5 shown inFIG. 5 e includes theslot 321, simultaneously with the increased length. Here, the length of the stop (A) is three or four times of the length from theslot 321 to an end of thehinge part 320. - The
experiment group 6 shown inFIG. 5 f includes thecut part 320, simultaneously with the increased length. - The
experiment group 7 shown inFIG. 5 g includes both of theslot 321 and thecut part 322, with the increased length. -
FIG. 6 shows the values of the shock transmitted to thetop cover 120, thelid 200 and thehinge member 300, when each hinge member according to the control group and the experimental groups is applied to a washing machine and when thelid 200 is dropped and collided against thetop cover 120. - The shock transmitted to the
lid 200 is reduced but the shock transmitted to thetop cover 120 is increased in theexperiment group 1, compared with the control group. - The shock transmitted to the
lid 200 is reduced but the shock transmitted to thetop cover 120 is increased in theexperiment group 2, compared with the control group. - The shock transmitted to the
lid 200 is reduced but the shock transmitted to thetop cover 120 is increased in theexperiment group 3 also, compared with the control group. - Both the shock transmitted to the lid and the shock transmitted to the
top cover 120 are reduced simultaneously in theexperimental group 4, compared with the control group. - Both the shock transmitted to the lid and the shock transmitted to the
top cover 120 are reduced simultaneously in theexperimental group 5, compared with the control group. - The shock transmitted to the
lid 200 is reduced but the shock transmitted to thetop cover 120 is increased in theexperimental group 6, compared with the control group. - Both the shock transmitted to the lid and the shock transmitted to the
top cover 120 are reduced simultaneously in theexperimental group 7, compared with the control group. - In reference to the
experimental groups 1 to 7, theexperimental groups lid 200 and the shock transmitted to the top cover reduced simultaneously. Among these three groups, theexperimental group 7 has the least shocks transmitted to thelid 200 and thetop cover 120. - The inventor finds out that the
hinge member 300 of theexperimental group 7 is the most proper one to reduce the shocks transmitted to the lid and thetop cover 120. - That is, the length of the
cylindrical hinge part 320 is increased 3 mm from 11.5 mm to 14.5 mm and both of theslot 321 and thecut part 322 are formed at thehinge part 320. - As mentioned above, according to the
washing machine 100 adapting thehinge member 300 of the present invention, the shock received by thelid 200 and thetop cove 120 may be reduced and damage of thelid 200 and thetop cover 120 may be prevented accordingly, even if the user drops thelid 200 to close theopening 121 of thetop cover 120. - It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
